I tried to upload a STEP file three times. Once, when I created a Project I added the Step file and it said it was succesfull but when I opened up the project there was no geometry. Once from within the project I uploaded a STEP file with the same results and once it gave me an error.

Sorry that you’re experiencing issues with the platform. Our back-end team is looking into it and is trying to fix it as soon as possible! Apologies for the lost productivity and the hassle on your end! I’ll get back to you once it’s fixed.

I’m Anatol and responsible for what we call Platform Engineering at SimScale - that is, everything related to the platfom that underlies SimScale: data storage, executing jobs, getting data from and to your browser etc.

We recently replaced a critical part of our system, the long-term storage of customer data, with a new component that will allow us to scale pretty much indefinitely in terms of storage. We tested that component for several weeks on several development systems, but obviously some issues that are now appearing at the scale of our production system were not found by those tests. This is why uploads were failing and currently are again.

Yesterday, we thought we had a workaround for what is happening to uploads, but it seems like that was not enough. We will be working on a proper fix and let you know once we are confident we have found and properly fixed the issue. Until then, we can resolve the issue temporarily whenever it arises, and will do so (I just did that and it works again).

Actually already on Friday, we released something that should make this more stable, and so far it’s looking good. We will continue to improve this part of the system however (not just stability, but also speed).

Thanks again for the patience - and letting us know when something doesn’t work! This is important to us.

Sorry this happened again - it was the same component, behaving badly in a different way than before. We could resolve the problem again temporarily (around 2:45 PM CEST/8:45 AM EDT), but another root-cause fix will be required.

We will improve our monitoring of this component to detect this failure mode, too, and let you know as soon as we are convinced we have a permanent solution.
